Title: Process for the manufacture of translucent polycrystalline alumina bodies
Inventor: PUSKAS FERENC
IPC: C04B35/00
Filed: 1973-07-10
Granted: 1979-05-29
Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides a process and composition for fabricating tubular shaped, polycrystalline, translucent, dense alumina bodies for use as lamp containment structures in relatively high pressure sodium vapor lamps wherein a mixture comprising finely divided aluminium oxide, which is plasticized with a relatively small quantity of organic compound, is charged to a cold flow process.  A relatively high continuous pressure is exerted on the mixture in the cold flow press thereby causing the mixture to flow continuously from the press in the shape of an integral, elongated, tubular body.  The body is then placed in a first heated environment at a temperature sufficient to cause the egress of the plasticizer from the body.  The body is subsequently placed in a second heated environment for sintering.

Abstract: PHASE DEMODULATOR               ABSTRACT OF THE DISCLOSURE    A reference carrier signal is combined with a phase modu-lated signal of the same basic frequency to generate an output signal the amplitude of which varies in accordance with the phase difference between the phase modulated signal and the reference carrier.  The permissible modulation angle is in-creased by vectorally adding the phase modulated signal with a reference signal having a phase different from the compari-son reference carrier.  The vector sum signal is amplitude-limited so that the signal produced by the comparison will only be responsive to phase angle and not amplitude.
